Quick Summary
- The PCM in a 2000 Chrysler Cirrus controls fuel delivery, ignition timing, and transmission shifts.
- Replacement typically requires 0.4 hours of labor, plus 0.5 hours for relearn procedures.
- A new module must be programmed with the vehicle’s VIN and mileage using a DRB scan tool.
- Common symptoms include no-start conditions, stalling, or internal control module memory checksum error.
- Flagship One units arrive pre-programmed, eliminating the need for VIN and mileage input.
If your 2000 Chrysler Cirrus is experiencing unexplained stalling, rough idling, or failure to start, the powertrain control module (PCM) may be the culprit. This critical component oversees engine and transmission functions, ensuring smooth operation. When it fails, symptoms can range from minor drivability issues to complete immobilization. Replacing the PCM involves straightforward labor, but proper programming is essential to restore full functionality. Understanding the process helps you avoid unnecessary delays and ensures your vehicle runs as intended.
What the PCM Does in a 2000 Chrysler Cirrus
In your 2000 Chrysler Cirrus, the powertrain control module acts as the brain for engine and transmission operations. It processes data from sensors to adjust fuel injection, ignition timing, and shift points, optimizing performance and efficiency. A malfunctioning PCM may disrupt these functions, leading to poor drivability or even a no-start condition. When replacement becomes necessary, selecting replacement powertrain control modules for the Chrysler Cirrus ensures compatibility and reliability. The module’s role is central to your vehicle’s operation, making its proper function non-negotiable for consistent performance.
Where the PCM Is Located and What Replacement Involves
The PCM in your 2000 Chrysler Cirrus is located in the engine compartment, simplifying access for replacement. Removing and reinstalling the module typically requires 0.4 hours of labor, according to factory estimates. The process involves disconnecting the battery, unplugging the electrical connectors, and removing the mounting hardware. No specialized tools are required beyond basic hand tools, but care should be taken to avoid damaging the connectors or the module itself during handling. Once installed, the new unit must be programmed to match your vehicle’s specifications.
How to Reach the PCM on the 2000 Chrysler Cirrus
- Disconnect negative cable from auxiliary jumper terminal Auxiliary Jumper Terminal.
- Disconnect both 40-way connectors from PCM.
- Remove screws attaching PCM to bracket PCM Bracket Screws.
- Lift PCM up to remove it from vehicle.
Work with the ignition off, and treat the module as static-sensitive: avoid touching the connector pins at any point.
| Operation | Configuration | Book Time |
|---|---|---|
| Powertrain Control Module Relearn | All configurations | 0.5 hr |
| Powertrain Control Module R&R | All configurations | 0.4 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module R&R | All configurations | 0.4 hr |
Programming Requirements After Replacement
After installing a new PCM in your 2000 Chrysler Cirrus, the factory procedure requires reprogramming the module with the vehicle’s original VIN and mileage using a DRB scan tool. This step ensures the module communicates correctly with the engine and transmission systems. However, a VIN-programmed replacement unit from Flagship One arrives ready for installation, eliminating the need for this additional step. This saves time and reduces the risk of programming errors, allowing your vehicle to return to service more quickly.
Symptoms of a Failing PCM
A failing PCM in your 2000 Chrysler Cirrus may cause a variety of symptoms. Common issues include intermittent stalling, rough idling, or a no-start condition. You might also notice poor acceleration, erratic shifting, or the illumination of the check engine light. Diagnostic trouble codes, such as internal control module memory checksum error, often accompany these symptoms, indicating a potential module failure. In some cases, the vehicle may enter a limp-home mode, limiting engine power to prevent further damage. Addressing these signs promptly can prevent more severe drivability problems.
Factory Service Bulletins Worth Knowing
Chrysler issued service bulletin #08-030-06 Rev. A to address powertrain control module initialization procedures for vehicles like your 2000 Chrysler Cirrus. The bulletin outlines steps to ensure proper communication between the PCM and other vehicle systems after replacement or reprogramming. Following these guidelines can help prevent recurring issues and ensure the module functions as intended.

Protecting the PCM in Your 2000 Chrysler Cirrus
- Maintain a healthy charging system to prevent voltage spikes that may damage the PCM.
- Ensure all electrical connectors and grounds are clean and securely fastened.
- Avoid jump-starting the vehicle with incorrect voltage or polarity.
- Address diagnostic trouble codes promptly to prevent cascading failures.
- Keep the PCM connector seals intact to prevent moisture intrusion.
- Use a battery maintainer during long periods of inactivity to preserve module integrity.
Frequently Asked Questions
How do I know if my 2000 Chrysler Cirrus PCM is failing?
Common signs include stalling, rough idling, or a no-start condition. The check engine light may illuminate, and diagnostic trouble codes like P0601 may appear. If the vehicle exhibits these symptoms, the PCM should be tested for proper function.
Can I replace the PCM in my 2000 Chrysler Cirrus myself?
Replacement is straightforward if you have basic mechanical skills and tools. However, the new module must be programmed with the vehicle’s VIN and mileage, which requires a DRB scan tool. A pre-programmed unit simplifies the process.
What happens if I don’t reprogram the PCM after replacement?
Without reprogramming, the PCM may not communicate correctly with the engine or transmission, leading to poor performance, stalling, or a no-start condition. Factory procedures require VIN and mileage input to ensure proper operation.
If your 2000 Chrysler Cirrus is experiencing PCM-related issues, you have options for repair or replacement. A new or refurbished module can restore functionality, but programming is critical. Pre-programmed units eliminate the need for additional steps, saving time and reducing the risk of errors. Consider your vehicle’s needs and choose the solution that best fits your situation.
